jdll'whom may' concern: r 'Be tknown that we, EDWARD-MEYER and' Spnrrrnrc's, citizens Aof the United` States, residui at- San Antonio, in the county of' 'Bexar andi tate of- Tex'as,`-have invented certain new fand useful Improvements in* Axle-Lubricators, of-vwhich the vfollowirg is a specification.

The present invention has for its primary object to provide animproved axle lubricatino' device which-is peculiarly designed so .as yto l be readily applied to` the hub of an ordinary wheel and which 'will operate in anetthe oilingto be done instantly without re- 'mo'ving thewheel, and'can be readily cleaned festive manner to convey oilor lubricantto the spindle and v'prevent the return thereofI of annular grooves Sa-and 8b. The cover 9 when the wheel is rotated.

The invention furthercontemplates 'a lubricating attachment of the character set forthzwhich may b e easily manipulated withont. thefuse of a wrench or other tool, permits incase of clogging through the use of'impure tion of 4the invention and and also to acqulre a knowledge ofv the detailsof construction and.

A i the means of effecting Vthe result, reference is t'b had to the following description and ac` vce panyingv drawings, inwhich:

4 Figure 1 is a longitudinal lsectional view showing the invention applied to. the hub of `a-wheel, portions being broken away. Fig. 2 is an enlarged sectional view through the lubricator cup. Fig. 3 is a transverse sectional view on the line 3-3 of Fig. Fig. 4 is a top planview of the cover. Fig. 5 is a view showinga split clamping ring for applying the lubricator to the wheel hub.

Corresponding and like parts are referred to in the following description and indicated in all the views ot the drawings by the same reference characters.

Referringto the -drawing the numeral 1 designates the' hubl of an ordinary wheel which is mounted upon the spindle 2 at one end of an axle 3, the said members being of the conventional construction and the upper portion of the spindle beingshown as having a 'longitudinal-groove 4 therein for distributing the lubricant? The oil reservoir or cup 5 is mounted upon .a base which is secured in any suitable manner t the hub 1, and this be in the nature of a'rigid band 6,' or a split band-6', the ends of the. said split band overlapping each otherl and having a .spring action'whichenables them toacconh modate 'themselves te various, sizes got' hubs.

In'either instance however one endfofthe band is designedto roject beyond the inner.

end of the hub an" to cooperate .with the .bolster j' to exclude sandk from the spindle. l,The oil reservoir 5 projects beyond the edge fof the bandv and communicates `ias-*ith an voil tube 7 extending from the 'exterior'of .the hub to the spindle receiving opening therein .and designed to lead the lubricantlr-oni the reservoir to the spindle. vThe .reservoir 5 may be of any approved shape, althoughin ythe present instance it .is -shownas cylindrical, and lis-provided upon its interior with a pair for closing the reservoir-'is formedwithwan annular llange 10 fitting closely within ythe reservoir and having a width corresponding approximately Avpair of spring strips 11 are secured tothe interior of the flange 10v at approximately diametrically opposite points, thefree ends of the spring strips being received withinlrecesses 12 formed -in the bodyv portion ofthe cover 9. Projecting from eachot-the spring strips 11 is a pair of locking lugs 13, the saidlugs being designed to pass through openings inthe flangeso as to engage the grooves 8? and 8b in the reservoir. Spindles 14 have a threaded connection with the Jfree'e'nd's ofthe springs 11 and pass loosely through the cover 9 where they terminate in finger-pieces 15. lt will thus .be apparentthat by pressing inwardly upon' these inger-piecesthe s ring strips 11 will be forced away from the fiange '10 and the locking lugs 13 retracted so as to clear 4the walls of the reservoirwhen the cover is being therefrom. When it is desired to lubricate the wheel, the lfinger-pieces 15 lare pressed inwardly to lretract the lugs 13 and the cover 9 removed placed 4in Vpositionor removed from the oil reservoir 5. After the 'oilor lubricant has been placed within the reservoir, the cover is again applied thereto and the lubricant caused to liow through the tube 7 which ydelivers it to the spindle 2. the cover is in position an air chamber is formed-above the lubricant and as the cover isforced inwardly lthe air is compressed and serve-s toforce the lubricant through the feed tu'be. Should it only be desired to use a porf. tion of the lubricant the lower set of lugs 413 are caused to engagev the upper groove 8a and the cover thereby locked in position with-the to the depth of the reservoir. 1

Froni'tlie foregoing description it will be readily apparent that the iinproved lubri- -cati'ng .device can be1 readil)v applied to the liub'of an ordinary wheel and provides both a sand-band for excluding foreign inatterfroin the spindle and also enables the lubricanttov be ap lied to the spindle without the Inecessity oi' removing the wheel.-

It inay "also be mentioned 'that the feed tube 7 is preferably forined separate froni the reservoir. and is provided at its upper end with a flange 7 a received within a' corresponding depression in the bottoni of the reservoir. This inanner of constructing the device enables t-he tube vto be readily. replaced should it bedaniaged by any accident., and also facilitat-es .cleaning 'thereof should it beco-nie clogged through the use of impure oil.

Having thus described the invention, what is claimed asnew is:v 1. An axle lubricator comprising a band adapted to be applied to the hub' 5f a wheel7 an oil cup carried by theband and projecting "n beyond an edge of the saine,'and a feed tube leading froin the projecting portion of the cup.

2. An axle lubricator comprising a split band adapted to be applied to the hub of a, wheel, an oilv cup carried by the split band and projecting beyond an edge of the same, and a feed tube leading froni theprojecting portion ofthe cup.4 1

3. In a lubricator, the combination of a reservoir fornied with lan annular groove, a cover provided with a flange adapted to be received within t-he reservoir, a spring carried by the flange, a lug projecting from the spring and extending through the flange for coper- 'ation with the groove to hold the cover in position,l and av feed tube leading from the reservoir. y *l y 4. In a lubrieatorJ the combination of a reservoir forined with a pair of annular grooves; a cover provided with a flange adapted to be received within'the reservoir, a spring carried by the flange.; lugs projecting from the spring and extending through the flange for cooperation with the' grooves to jhold theeover in an adjust-ed position, and a feed tube leading from the reservoir.

5. In alubricator, tlie'combination ofa lreservoir having a pair of annular grooves Aformed in the. interior walls thereof, a coverV therefor, the said cover being formed with an annular flange adapted to be received within the reservoir` -`a spring strip applied to lthe flange and provided Wit-ha lair o ocking lugs adapted to cooperate wit i the annular grooves to lock the cover in position with the flange either entirely or partiallyT received within the reservoir, ,and ineans forfeeding lubricant from the reservoir. .l
